Agua "Sin Gas"

I remember many years ago traveling through Europe for my university graduation present. My buddies and I drank [alcohol] our way through a few of the countries over there. I also remember being constantly amazed when the waiters would ask us if we wanted water with, or without gas. Who drinks carbonated water (without vodka)?

Well, I am one of those guys now. I don't get it everytime, but occassionally. It fills another need, fits in with certain times better, and I can make my obnoxious hand gestures with more authority when holding a glass of carbonated water (versus plain boring water). What is happening to me? I love it...
